The Precambrian Time
The geological events in the Mesozoic Era include, but are not limited to...The breaking up of Pangaea.The great meteor that hit earth destroying the dinosaurs
The Paleozoic era was the era when oxygen-breathing organisms first thrived.
We are in the Cenezoic Era, the Quaternary Period, and the Holocene Epoch.
The Cenozoic.
Paleozoic, Mesozoic and Cenozoic are examples of geological era from the Phanerozoic Eon.
The oldest geological era is the Precambrian period. It is the period of Earth's formation, as well as the origin of the first single and multi-celled organisms.
During the Archean Eon life started and was dominated by one-celled prokaryotic life forms. Eukaryotic one-celled organisms became dominant in the Proterozoic Eon. Multicellular organisms ruled the planet during the eon known as the Phanerozoic.
